The Pawnee and the Sioux hate each other. They are both there protesting, as are many other tribes. It’s probably been over hundred years since any Pawnee have went that far into ‘enemy’ land. Makes the shia/sunni conflict look civil.
“The Pawnee and the Sioux hate each other.”
With the Pawnee stealing young girls from the Sioux for their Morning Star Ceremony I can understand why they hate each other.
